DBpedia Spotlight looks for ~3.5M things of unknown or ~320 known types in text and tries to link them to their global unique identifiers in DBpedia.

Go to our Demonstration page, copy+paste some text and play with the parameters to see how it works.

You can use our demonstration Web Service directly from your application.

curl http://spotlight.dbpedia.org/rest/annotate \
  --data-urlencode "text=President Obama called Wednesday on Congress to extend a tax break
  for students included in last year's economic stimulus package, arguing
  that the policy provides more generous assistance." \
  --data "confidence=0.2" \
  --data "support=20"

If you need service reliability and lower response times, you can run DBpedia Spotlight in your own In-House Server.

wget http://spotlight.dbpedia.org/download/release-0.6/dbpedia-spotlight-quickstart-0.6.5.zip
unzip dbpedia-spotlight-quickstart-0.6.5.zip
cd dbpedia-spotlight-quickstart-0.6.5/
./run.sh
